Airhead? Here I was thinking I was intuitive.

Oh! Just shut up about shariah already! What do you mean behind times? Shariah hasn't even taken full effect yet, but it will, Gods willing.

Like I always say, Sharks>salmon.

When the seagulls follow the trawler it's because sardines will be thrown into the sea.

What happens when there are no sardines?

Don't worry, sassenach. [/s] [Soon the south will be free of the north completely, [s]and the south can indulge in what ever brand of faggotry they want.[/quote][/s]
Make this very snappy. Your elites seems to love money more than your religion, so I doubt they would leave the wealthy southern region to satisfy their backward brothers and sisters in the north.

avalontony:
Even the so-called educated illiterates are in support of the women wearing hijab in the name of religion when a lot of people are dying on a daily basis from suicide bombers.

That is the scary part isn't it? Someone's feeling about their religion shouldn't excuse rational thinking... oh well *shrugs*.

RagnarLodbrok:
Of Course that's what you'd imagine, you're a bigot who hates northern muslims in specific.

Being tribalistic is normal, it's human nature but you're not tribalistic, you're a bigot.

I normally don't reply airheads, but I will take exception to you this time.
If dealing with facts makes me a bigot, then so be it. Majority of northern Muslims are a still behind the times. The wide support for sharia law in the north gives away the psyche of an average northern Muslim.
I don't give a damn too much, as long as you lots disease doesn't affect the south. So there..

lurther:
I have never been so touched. This your post is very cool and encouraging. I liked it. You are a true Muslim. It is few people like you that still makes we christain have faith that Muslim is not totally what we do think.

Post of the century Sir.

There are not many people that shares his views I would imagine

Talk about demotion. Wow.

IsraeliAIRFORCE:
Tinubu is now part of the problem according to Northern elites and politicians after handing the Presidency to the North on platter of gold.

Nigeria Politics has no empirical formula nor a logical sequence above regional sentiment and interest.

This is one of Nigeria fundamental problem. Seriously, Nigerians needs to make it less powerful and unattractive because until then you won't see any significant changes in the country.

Op do kegel. I heard it helps.

Teempakguy:
thank you very much.

check https://www.khanacademy.org you can learn from there too.

Teempakguy:

You're good!

Please recommend the math textbooks I can read.
I'm currently an O'level student.

Hey baby
Pretty petite
How are u today

hey fresh dude. I am good you know. Yourself?
What is happening with you today.

This is the solution for question 3. A quick explanation.
Equality occurs by having equilateral triangle on the sphere and then 5 points at each vertex.

Teempakguy:
oh really?
I find them rather difficult. Except number 4.

They are more like a brain teaser rather than a hard core math.

Teempakguy:
this is incorrect. We are asked to find the amount of time spent in the air After the height of 50m has being transversed. I think the best approach would be to find the final velocity at the foot of the jump and use it to calculate the time used in flight.

You are wrong. Anyways, check my subsequent answers

This is just a further mathematics. Don't see anything hard in these to be honest. This ain't no advanced calculus that's for sure.

Slimzjoe:
Sure... Why?

Well, that was my reply to adiwana. He doesn't seem to understand my solution.

Adiwana:
nawao

Adultnextdoor come and present your answer for question 3. So that I can determine whether you are right.

Slimzjoe:
Cc: Teempakguy
Johnydon22

Come solve this maths

Do you understand conservation of energy principle?

Adiwana:
aunty,pls i cant understand this oo...use x as your variable instead of a..thanks

hope you understand?

Adiwana:
aunty,pls i cant understand this oo...use x as your variable instead of a..thanks

a is the alpha=30 degrees. It is very hard to type equations using phone. Can't be bothered to use Microsoft Word lol

solla22:
T is 11.9 Seconds

t is not 11.9. How did you solve it.

Obinoscopy:
You didn't make use of the coefficient of friction (0.05)?

Factoring the coeeficient of friction mean the net force on the skier on the ski jump parallel to the ski jump surface is a combination of the gravitation force and the frictional force,
For simplicity
F(net)= mg (sinθ -μcosθ)

The net work done on the skier as he travels down the jump is W= FL where L is the length of the jump, L=50/sinθ


By the work-energy theorem the skier launches horizontally from the bottom of the jump with a speed
v(=(2gh(1-μcotθ))^2
After the skier launches (and treating the launch point as x,y=0), the horizontal and vertical position of the skier are
and at the moment of impact, (x,y)=(0,0)
x=vt, y=-1/2 (gt)
The landing spot is on the line , so we have a system of equations we can solve for t=3.794 seconds.
v=29.919m/s check attached pictures to see how I solved for v


More detailed calculation using conservation energy. ..

Using the conservation of energy principle, the work done by friction must be equal to the change in the mechanical energy of the system (h = 50m, alpha = 30°),
(1/2mv^2)-mgh=-μmgcosθ(h/sin30)
This implies
v=sqrt (2gh (1-μcot30))
During the fall, using parallel (x axis pointing 'downwards') and perpendicular (y axis pointing 'upwards') axes in respect to the hill, we can write down the variation of y with time as
y=y[size=4pt]0[/size]+vsin30t-(g cos at^2)/2)
Setting y=0 and solving for t(h'=5m)
t=vtana/g (1+sqrt (1+(2gh'/v^2 tana^2)))=3.795

Adultnextdoor:
......now.... This is a complete and correct calculation.......i'll give you 10/10....

Just an explanation, thus it's not even complete. Shows you don't even know what you are talking about.

Adultnextdoor:
......it doesn't matter whether he is the op or not......his calculation is incomplete but its obvious he has an idea!

Hence you are so good in maths, can you solve question three so that we know your level? Or give us theoretical background answer to the question.
Bear in mind I have just solved it.

Okay I will bite for 3.

I need to dig out my further math A-level text book to solve 3. When I have time.

Number 4 is quite easy too as well.
If you think about this. The total amount spent in the air by the skier is the same as the time taken to slope down(starting from the horizontal position) the whole distance of 50meters.
thus distance gives =1/2 at t^2
Therefore 50=1/2 × gt^2 = 1/2 (9.8 )t^2 =50 solve for t
T= 3.2 seconds

Very easy because time only depends on gravity in this case.

Number 2. Attempts. The second easiest after 4

I can attempt 2.

UnknownT:
It's not a new thing op. Pre BH, when religious crises and killings were the main thing. The Christians were targeted by mostly their Muslim neighbours

In the North, yes. It's unfair on the SW Muslims for you guys to lump them together with their northern counterparts. Let's be sensitive please.
Say no more.

I will rather you didn't make this post about religion because SW Muslims doesn't kill for religious reasons.

light004:
I really do not share in all your views. Some I reckon with but others I have a strong reservation. I think the idea that one man is what is wrong with Nigeria is totally false and also one man has the magic wand to solve all the problems is also a fallacy. The challenges in Nigeria are deep and they are both internal and external. We need to solve the internal before we move to solve the external.

The internal has to do with the people both the leaders and the followers. The leaders do what they do because the followers are docile and uninterested in the affairs of their nation so far their momentary needs are met. While the leaders understanding this exploit it to their benefits.

It was easy for the APC to ride to power because they understand the psyche of an average Nigeria. Filled with sentiments and hate, the average follower can be easily manipulated so far what he is hearing accords with his sentiment not minding the facts or reality. It's obviously with the bogus promises of the APC that they don't have a concrete plan for the Nation. Unachievable promises were made and yet no one questioned the ration or the logic we just believed and today the reality has set in. Empty treasury, I'm not a miracle worker, our party manifesto is not the bible or Quran and so can be changed, etc. A corrupt politician is celebrated in his community and protest organized to call for stoppage of his prosecution without due process to determine whether he is guilty or not and yet we demand a better Nigeria from our leaders. We must first purge ourselves of the poor mentally and orientation that just wants to grab everything without giving or service. We need to blame ourselves not the leaders because they are a reflection of us.

Nigeria will be great again whether as a single entity or dismembered entities but one thing stand no real development without the active participation of the people not just the leaders.

This is the best comment so far. Thanks for this.

ekiloui:
CramJones for the 1st time I agree with you!

I never campaigned for either GEJ or Buhari, although I always prayed Buhari would win, atleast for hope sake.

But what we need in this country is neither change nor transformation. We need a Revolution!

And only the youths can do this since our leaders (recycled politicians) won't let this nation progress

Indeed. Nigeria need a revolution. There are some institutions that needs to be destroyed and restructured. There are social issues like poverty, corruption, injustices etc that needs to be addressed. As long as Nigeria fails to do this, the country will keep going round in circles. The system is the problem.
